Metallafluorene have recently received much attention because of their unusual electronic properties. These unusual optical and electrical properties can be useful in electronic devices, such as electron transporting materials, light-emitting diodes (LEDs), and chemical sensors. It is also reported that silole-containing polymers are selective chemosensors for nitroarematec oxidants, including TNT. Detection has been achieved though fluorescence quenching of the silole by the electron-deficient analyte. The luminescence of silole is due to a σ*-π* LUMO stabilized though conjugation of the σ* orbital of the silicon chain with the π* orbital of the butadiene moiety. The selectivity of the sensor is due to the helical structure of metallafluorene, which permits the intercalation of planar nitroaromatics. Here we report the synthesis of new type of photoluminescent metallafluorene. New metallafluorene have been characterized by NMR, FT-IR, UV-vis absorption spectroscopy and X-ray single crystallography. Their optical characteristics have been also investigated using photoluminescence spectroscopy.
